Claims.

My present invention relates to plumbing systems and more particularly to an improved combination of a suspending :means for a plumbing fixture and a connection between the plumbing fixture and discharging means therefor.

Specifically, my present invention relates to means for making an air and gas-tight connection between a plumbing fixture, suspended from or supported on a wall or upright, and the long leg of a syphon associated with but separate from the plumbing fixture, the syphon long leg'being arranged to discharge into a soil or drain pipe. In order to maintain the integrity of the syphon structure between the plumbing fixture and the soil or drain pipe, and in order to ensure that no noxious gases escape into the room in which the plumbing fixture may be located, my invention provides for the suspension of the plumbing fixture in a manner wholly reheving the stated connection from support of the plumbing fixture.

A feature of my invention is an improved supporting means for plumbing fixtures in combination with a joint connection for the discharge parts of the fixture. Y

A feature of my invention is an improved means for securing and holding the fixture on a wall or other likesupport in combination with a readily accessible air and gas-tight joint connection between the discharge passage of a plumbing fixture and the long leg of a syphon.

Further features and objects of the invention will be more fully understood from the following detail description and the acompanying drawing, in which Fig. l is a vertical sectionthrough a portion of a syphon discharge type of plumbing fixture, such as a defecator, attached to a supporting wall, and illustrating a preferred type of air and gas tight connection between the Syphon parts.

Fig. 2 is a vertical section taken on line 22'of Fig. 1. 1

Fig. 3 is a horizontal section taken on line 3-3 of Fig. 2.

Referring to the drawing, [0 designates a plumbing fixture, here illustrated as a defecator, suspended from a vertical face of a wall H.

Such suspension is afiorded by channel. uprights 28, which may be component parts of the wall structure H, but in practice'preferably rest upon the floor of the building'and are suitably attached to an inner part of the building wall I I. The channel uprights 28 may each be provided with a vertical slot 29, of a width to allow free sliding vertical movement of the therein positioned bolts 30, to afford a range of adjustment of positioning of the fixture. Each of thebolts 30 is provided with a multi-sided head 3!, its other end being threaded to receive a cap nut 32, see Fig. 1. l i

Such channel uprights 28 may have secured;= thereto, or formed integral therewitlna member 33 extending from one lateral wall of the channel to the other, thereby'forming a pocket in which is housed the heads of the bolts 36. It is V preferable to initially install the uprights .28, 10 then to place the bolts 3!! in position in the respective slots 29 by passage of each bolt through the aforesaid pocket, the he'ads'of the bolts 38 being retained in such pockets, and being thus precluded from rotation. Thereafter the cap nuts 32 may be screwed onto the threaded ends of bolts 36 from the front of the wall Hyto position and sup-port the defecator, as will later appear. The portions of the wall H, adjacent to the protruding bolts 38 and other stated parts 2.0 may be cut away to permit vertical movement of such bolts in the slots 29 in the uprights 28, also to aiford access to the stated pockets, etc.

The upper portion of the apron of the illustrated defecator It is shown provided with elon- 25 gated vertical slots 34 through which freely pass the bolts 30; The height of the bolts 30 above the floor of the building is such that the seat portion of the defecator I I], when the same is in position, is at approximatelythe correct height above 30 the floor. Because of the presence of the clon gated slots 29, in the uprights 2'8 and the slots 34 in the defecator l0 respectively, the position of the defecator H! with respect to the floor of the building may be accurately determined after 35 which the cap nuts 32, above referred to, when tightened, secure the defecator rigidly in position, care being taken to place washers 35, orequiva: lent, between the cap nuts 32 and the outer face of the defecator l0. p 40 The. plumbing fixturelll has beenillustrated and referred to; as a defecator but obviously such fixture may be a sink, tub, lavatoryjor the like, the maintenance of the joint of its'trapway or other sealed discharge being essential and prescribed by public health laws. The inlet of the defecator is indicated at I2 and such inlet is con-.

nected by any suitable fitting l3, to the flush tank" M, or equivalent, fromwhich water or'othe'r 50 flushing fluid is supplied and by means of which the defecator is flushed. Below the inlet l2 and as an integral part of the defecator II], is formed a flange liprovided with a discharge opening IS;

the flange I5 is provided on opposite sides of the opening I6 with perforations IT, for a purpose to be hereinafter described.

The defecator I is provided with a discharge up-flow leg I8 which constitutes the short leg of asyphon and which communicates with the.

the discharge up-flow leg l8 of the defecator It.

Such long leg of a syphon is indicated by the reference numeral 19 and the entrance end thereof is of a diameter slightly less than the diameter of the opening l6 in the flange l of the defecator 'l 0. The syphon leg I 9 may be of any desired material, such as brass, lead or iron, and advantageously has the structural characteristics set forth in my co -pending application Ser. No. 4,620

. surrounding the end of the syphon leg 19, is a 7 packing 2|, of any suitable material, such as of rubber, cork, wicking, asbestos or the like,

Surrounding the long syphon leg is is a ring 22, the inner diameter of which is substantially equal to the diameter of the opening 16. Formed integral with the ring 22 and on the face thereof is an annular gland 23, the end of which may be bevelled, as shown in Figs. 1 and 3. The outer diameter of the gland 23 is slightly less than the diameter of the counter-bored portion 29' of th opening [6.

Formed integral with the ring 22, and arranged diametrically with respect to such ring are outwardly extending ears 24. Adjacent to the ends of such ears 24 are provided studs 25. The free ends of the studs 25 are threaded, as shown, and extend through the perforations II in the flange I5 of the defecator I0. 0n the threaded end of the studs 25 are'arranged washers 26 and nuts 21. The nuts 21 are employed toiadjustably s'ecure the ring 22 onto the defecator I 0 and to simultaneously force the gland 23 into the counter-bored portion 20 for the purpose of compressing packing 2| and thereby forcing such packing into engagement with the counter-bored portion 20 and the outer face of the end of the syphon leg [9. H

As the. connection between the discharge passage l8 of the plumbing fixture and the syphon leg [9 is .wholly free from strains and the stresses incident to. the support ofthe defecator ID, and

the, load when in use, the air or gas-tight joint between the elements constituting the syphon is normally assured. The type of joint is such, as shown, to afford full installation and adjustment from the front of the fixture I0.

From the above, it appears that the joint of the fixture to be sealingly closed. is'located rearwardly of the fixture and, usually concealed ina wall of a building or like normally inaccessible location. However, by my improvement, the'joint is completed in assembly and later adjusted by suitable" instrumentalities accessible fromv the front of the fixture.

While I have necessarily shown the preferred embodiment of my invention somewhat in detail, I may vary the size, shape and arrangementof parts comprising my improved device within relatively widelimits without departingfrom the spirit of the invention. 7
